“…The location of housing and enterprises determines the distribution of the population and employment, which constitutes the structure of urban land use. Meanwhile, urban land use structure affects traffic demand and road investment decisions by the government [40,41]. In recent years, more and more scholars have been trying to explore the relationship between land use and urban traffic from the perspective of spatial layout and traffic planning, and to analyze the coordination between them [42].…”

The implementation of the Beijing, Tianjin, and Hebei coordinated development strategy has seriously increased the influence of land use and urban traffic. Thus, understanding the coordination between urban land and transportation systems is important for the efficient and sustainable development of cities, especially in this rapidly urbanizing era. Urban–industrial land and highway networks are, respectively, primary types of urban land and transportation systems, and have significant impacts on social and economic development. However, limited studies have been conducted to examine the relationships between urban–industrial land and highway networks. Therefore, this paper aims to examine the coupling coordination relationship between urban–industrial land use efficiency, and the accessibility of the highway networks of cities. Specifically, in the context of the Beijing–Tianjin–Hebei (BTH) urban agglomeration, the coupling coordination between urban-industrial land use efficiency and accessibility of the highway traffic network was empirically analyzed. The results show that: (i) The differences in urban-industrial land use efficiency in the BTH region are significant. Capital cities in the BTH urban agglomeration have higher economic, social, and comprehensive efficiency, while in industrial cities, the use of urban–industrial land should prioritize ecological and environmental issues. (ii) Because of its good geographical location Beijing has the best accessibility, with an accessibility index of 1.416, while Qinhuangdao had the lowest accessibility index of 0.039. (iii) In most BTH cities, the urban-industrial comprehensive land use level has fallen behind the highway network development level. The results of this study can provide references for the coordinated development of the BTH urban agglomeration.

“…Cool material, urban greenery, water bodies, and urban design that can weaken heat source strength and promote excess urban heat dissipation are primary strategies and techniques for urban cooling [11,12,13]. Among them, green roofs, involving the planting of vegetation on building rooftops, is thought as an effective approach due to evapotranspiration and shading effects [14,15,16].…”

Growing and densifying cities set a challenge for preserving and enhancing green spaces to cool urban spaces. Green roofs, involving the planting of vegetation on rooftops, are regarded as an alternative approach to enhancing urban greenery and urban cooling. For better cooling performances, it is essential to reasonably configure green roofs, especially in real and complex neighborhoods. Therefore, the aim of this paper is to investigate the impact of morphological characteristics of green roofs on pedestrian cooling in real and complex neighborhoods. In specific, based on an ENVI-met model, we studied the effect of greening layout, coverage ratio, vegetation height, and building height on pedestrian air temperature reduction in the tropical city of Hangzhou, China. Results indicate green roofs could generate moderate effects on pedestrian air temperature reduction (around 0.10–0.30 °C), while achieving a cooling performance of 0.82 °C. Green roofs in upwind zones were able to generate the most favorable cooling performance, while green roofs in downwind zones made slight differences to pedestrian thermal environments. Green roofs with a low coverage ratio were not useful for lowering pedestrian temperature, and a greening coverage ratio of 25–75% in upwind zones was cost-effective in real neighborhoods. Locations that were horizontally close to green roofs enjoyed better cooling performances. Increasing vegetation height could strengthen cooling effects of green roofs, while an increase in building height weakened the cooling performance. Nevertheless, higher building height could enhance pedestrian cooling performances because of building shading effects. In addition, because of wind effects and building shading, building height limits for the cooling performance of green roofs could be higher than 60 m.

The subjective thermal comfort intervention of landscape elements has been few characterized in previous studies. Therefore, we conducted field studies at eight open spaces in the residential areas of Guangzhou, a city with a humid subtropical climate in China. Data based on physical measurements and questionnaire surveys were collected under a variety of weather conditions during summer and winter. The survey showed the percentage of 'Neutral' votes was generally higher in winter (34.4%) than in summer (20.2%), and the percentage of people who felt "hot" was dominant (43.9%) in summer. A new empirical model was developed according to microclimatic and subjective criteria, which considers air temperature, solar radiation, and wind speed. According to the empirical model in summer, a decrease of 84 W/m 2 in global radiation or an increase of 0.35 m/s in wind speed would have the same effects on thermal perception as a drop of 1 °C in air temperature. A similar analysis could be conducted with the winter model, a change of 20 W/m 2 in global radiation or a change of 0.10 m/s in wind speed have the same effects as a change of 1 °C in air temperature. Furthermore, the thermal comfort intervention of tree, shrubs, reflective surface and pervious ground were quantitatively analyzed in winter and summer based on the empirical model. Based on the analysis, we proposed that large broad-leaved trees and pervious ground were more conducive to the improvement of thermal acceptability during different seasons in hot and humid areas of China. The results showed that in summer, the total acceptable area
